NIN IAN PROCTOR, CHARLES EDIVARD FRASER, AND HAROLD MARK CARTER, OFLEEDS, AND ARTHUR MIDDLETON, OF BEN RHYDDING, ENGLAND.

MACHINE FOR THE MANUFACTURE OF BRICKS AND BRIQUETS.

SPECIFICATION forming part of Letters Patent No. 449,089, dated March24, 1891. Applicationfiled September 16, 1889. Serial No. 324,097. (Nomodel.) Patented in England January 9, 18B9,No.409.

To all whom it may concern.-

Be it known that we, N INIAN PROOTOR, CHARLEs EDWARD FRASER, and HAROLDMARK CARTER, residing at Leeds, and ARTHUR MIDDLETON, residing at BenRhydding, all in the county of York, England, subjects of the Queen ofGreat Britain and Ireland, have invented new and useful Improvements inMachines for the Manufacture of Bricks and Briquets, (for which a patenthas been granted us in Great Britain, dated January 9,1889, No. 409,) ofwhich the following is a full, clear, and exact description.

Our invention has reference more especially to means or apparatus forthe manufacture of bricks and briquets, consisting of mixtures orcombinations of material to be used for fuel; but it may also beemployed for the manufacture of bricks or briquets for other purposes.

Figure l is a longitudinal section of machine; Fig. 2, an end elevationof feeding end of machine; Fig. 3, an end elevation of brick or briquetforming end of machine. Fig. 4: is a plan looking on the top; Fig. 5,elevation of mixing and feeding knives or blades, and Fig. 6 part sideelevation.

On suitable supports A we mount a cylinder B, having the covers C and Dat its ends, and through the cylinder B is provided a shaft E, havingits bearings in the cylindercovers C and D. On the shaft E are fittedand fixed the mixers and feeders F in a spiral direction, as shown atFig. 1, these being for mixing and feeding forward the material which ispassed into the cylinder B. At one end and 011 the top side of thecylinder B is provided a hopper G, through which the materialis fedalternately into the intermediate chambers H, provided in the revolvingdrum J, and allowed to fall in the cylinder B at- K as each chamber Hcomes round to the lower position shown in drawings. The required motionis transmitted to the drum J, also to the mixers and feeders F, throughgearing L from driving-shaft M.

The amount of composition or material deposited into the cylinder B fromeach chamber I-I depends upon the size of such chamber H, and such sizeis dependent upon that of the brick or briquets, as it is the intentionof this machine that the amount of material fed into the cylinder shouldcorrespond with the amount of material let out of the cylinder forforming the bricks or briquets. The material, after being dropped in thecylinder at. K, is mixed, fed forward, and pushed through opening N incylinder-cover C into box 0, from whence it is forced, by means of theplunger P, alternately into the molds R, provided in the revolving drumsS, such drums having trunnions '1, whereby it is mounted and carried inbearings U. The required intermittent rotary motion is imparted from thedisk or crank V, provided on the crossshaft W, to the revolving drum Sthrough hooked connecting-rod X andpins or studs Y, provided in the sideof the drum-disk S. The required vertical intermittent reciprocatingmotion is imparted to the plunger P from the hooked connecting-rod X,through bell-crank lever Z, vertical rods 1, and crosshead 2, suchcross-head 2 being attached to the plunger P in the ordinary way. Motionis imparted to the cross-shaft W by gearing 3 from driving-shaft M. Ineach of the molds R in the drum S is provided a plate 4. The two platesin opposite molds are connected together bya rod or rods 5, so that asthe material from the cylinder is being forced into the top mold, asshown in the drawings, motion is transmitted to the plate in the .lowermold, which forces the previously formed brick or briquet out onto atable or other convenient receptacle, and while this is going on v ahorizontal plunger 6 moves forward and presses the material to therequired extent in the then horizontal mold, this movement .beingeffected by the crank 7 on the cross-shaft \V through the adjustableconnecting-rod 8 0 and slide-block 9. A spring 10 may be used betweenthe pressing-plungerti and the slideblock 9, so as to prevent any unduestrain upon the machine.

Under the cylinder B is provided a steam- 5 chest 11, into which steamis admitted by ordinary means and allowed to pass upward throughsuitable openings or perforations 12 into the cylinderB around and amongthe material during the operation of mixing and moving forward of thematerial. The Water or condensed steam falls to the bottom of thesteam-chest and can be drawn or let oif at any time, when required,through suitable or ordinary medium.

\Ve claim as our invention- 1. In a brick and briquet machine, thecombination, with a drum provided with a plurality of chambers, of acylinder, and steamchest provided with perforations, and driving-shaftM, whereby motion is imparted through suitable gearing to both thecylinder and drum at the same time, substantially as set forth.

2. In abrick and briquet machine, the combination of a crank or disk V,hooked connecting-rod X, bell-crank lever Z, vertical rods 1, cross-head2, plunger P, plunger-box O, and mold-drum S with its molds R,substantially as described.

3. The combination of supports A, cylinder B, with its end covers (J andD, shaft E, feeders or mixers F, hopper G, with its revolving chambereddrum J, gearing L, driving-shaft M, plunger-box O, plunger P, re-

volving drum S, with its molds R, and trunnions '1, bearings U, disk orcrank V, crossshaft \V, hooked connecting-rod X, disk S, pins or studsY, bell-crank lever Z, vertical rods 1, cross-head 2, gearing 3, plates4, rod or rods 5, plunger 6, crank 7, connecting-rod 8, slide-block 9,spring 10, steam-chest 11, and openings or perforations 12, forming thebrick and briquet machine, substantially as described.
